Q
Q: A solenoid produces a magnetic field similar to that of a bar magnet. What is the main factor that affects the strength of the magnetic field in a solenoid? (2021)
Solution: The strength of the magnetic field in a solenoid is primarily affected by the number of turns per unit length and the current flowing through it.
Steps: 5
Step 1: Understand what a solenoid is. A solenoid is a coil of wire that creates a magnetic field when electricity flows through it.
Step 2: Know that the strength of the magnetic field is similar to that of a bar magnet.
Step 3: Identify the two main factors that affect the strength of the magnetic field in a solenoid: the number of turns of wire and the amount of electric current.
Step 4: Realize that more turns of wire (coils) per unit length will create a stronger magnetic field.
Step 5: Understand that increasing the current flowing through the solenoid also increases the strength of the magnetic field.
